Claude Haiku 5.5 matches GPT-6 Luna at $0.10/$0.50 per million tokens and beats it on Anthropic's evals, but prompts over 100K tokens cost 5x and its tokenizer counts about 30% more tokens than Haiku 4.5. Short-prompt classification and routing get the big saving; compaction and long-context work get much less.

Claude Sonnet 5 and GPT-5.6 Terra both list at $2 per million input tokens. On the same workload Sonnet 5 bills 15% more, because Claude 4.7 and later tokenize the same text into roughly 30% more tokens. Prices, latency and governance terms compared as of 5 August 2026.
